What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
Latest, I ran the built in updater and it said I’m up to date.
Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
Yes, I m using video from a Paralenz Vaquita. It’s in the same format as used for YouTube. The source and export file extension are the same. When I add a white balance filter to a video segment, then use the eye dropper to pick white, the color patch turns black and the video goes completely black. If I pick colors manually for the color patch the white balance works well.
It seems to be only this file format that has issues as I opened an older project taped with a go pro knock off and things worked well.
There seems to be a related post about unbuntu’s color picker.
Does any of this sound familiar?
Apologies for the imprecision, I’m writing this in my car the next day. Hoping I can get an answer. If not I’ll post later with more precision.
When using the eye dropper drag a small rectangle instead of single click. Single click grabs one pixel that is difficult for you to pick precisely. The rectangle chooses an average of all pixels in the rectangle. Otherwise, it is impossible that this tool behavior is different based on the video format.
There is no easy workaround because there is inconsistency in the color dialogs on Linux depending on your desktop and build, etc. I have not reproduced the problem you describe, but I vaguely recall a reported problem on Wayland.
It’s weird the color picker next to pick neutral color does not work. But if I click the color swatch and then click the custom color. And then the color picker there it gets a color sample and the white balance seems to work.
I figured it out and it’s the WEIRDEST thing. I’m hoping @shotcut can explain it. I have a dual monitor set up. When I move the Shotcut window on the primary monitor, the white balance filter works. Upon dragging the window into my second monitor, it does the black screen error.
Is that a driver thing? That just doesn’t make sense to me, but it’s clear to me that it won’t work on that second monitor.
